Caveats
Cisco CKM Supports Spectralink Phones
Cisco CKM (CCKM) key management is designed to support voice clients that require minimal roaming
times. To date, CCKM supports only Spectralink Wireless Phones. Other voice clients have not been
tested with CCKM and are not supported.
times. To date, CCKM supports only Spectralink Wireless Phones. Other voice clients have not been
tested with CCKM and are not supported.
Non-Cisco Aironet Clients Sometimes Fail 802.1x Authentication
Some non-Cisco Aironet client adapters do not perform 802.1x authentication to the access point unless
you configure Open authentication with EAP. To allow both Cisco Aironet clients using LEAP and
non-Cisco Aironet clients using LEAP to associate using the same SSID, you might need to configure
the SSID for both Network EAP authentication and Open authentication with EAP.

Open Caveats
These caveats are open in Cisco IOS Release 12.2(13)JA4:
•
CSCeb02792—The 802.11a radio in 1200 series access points sometimes erroneously reports 100%
busy for all frequencies when you run the Carrier Busy test.

•
CSCeb52431—When logging into a TACACS+ server, 1100 series access points sometimes send
hundreds of additional authentication requests to the server after a successful authentication.

•
CSCeb50727—Unpowered 1100 series access points sometimes cause a loopback when connected
to switches without loopback detection. When you connect an unpowered 1100 series access point
to some switches without loopback detection, the access point sometimes causes a loopback. To
avoid this problem, make sure loopback detection is enabled on the switch to which the access point
is connected. If your switch does not have loopback detection, disconnect the access point from the
switch when the access point power is off.

•
CSCec23329—Access points with PMIP enabled sometimes misinterpret an ARP sent by some
client devices that check to make sure that their IP addresses are not in use. When the access point
receives the ARP from the client, the access point interprets the ARP as a DHCP request and disables
PMIP for the client session.

Workaround: If possible, disable the feature on the client device that automatically sends an ARP to
the access point to check IP address availability.

CSCec25559—When both 802.11g and 802.11a client devices transmit data simultaneously to the
802.11g and 802.11a radios in a 1200 series access point, the throughput of the 802.11a radio might
decrease.
